### 小案例 ###

*  `onsubmit`表单提交事件

我们希望提交如下图的的表单，当我们点击按钮提交之后我们就可以成功提交表单。

**完整代码**

<!DOCTYPE html>
    <html lang="en">
    <head>
      <meta charset="UTF-8">
      <title>Title</title>
    </head>
    <body>
      <form id="register" action="#" >
          <input type="text" name="username" />
          <input type="submit" value="提交">
      </form>
      <script>
          document.getElementById("register").onsubmit = function (){
        
              //onsubmit 返回true，则表单会被提交，返回false，则表单不提交
              return true;
          }
      </script>
    </body>
    </html>
